NIGP 92558: Irrigation; Drainage; Flood Control/Engineering

NIGP 92558 Irrigation; Drainage; Flood Control/Engineering is an Item code under which state and local governments procure engineering design, construction, and consulting services for stormwater infrastructure, flood mitigation, drainage system improvements, and related water management projects. Recent state and local solicitations show activity concentrated on design services for drainage and stormwater retrofits, construction management for flood control improvements, and feasibility studies for watershed and conveyance system upgrades. Issuing bodies span municipalities (Town of Parker, Colorado; City of Orlando, Florida; City of Tallahassee, Florida), counties (Collier County, Florida; Greenville County, South Carolina; Hamilton County, Ohio; Pasco County, Florida), water and utility districts (West Basin Municipal Water District, California; Brazos River Authority, Texas), school districts (Hillsborough County Public Schools, Florida; Hutto Independent School District, Texas), and special-purpose authorities (Georgia World Congress Center Authority, Metropolitan Area Planning Council, Massachusetts). The work being solicited ranges from preliminary assessments and hydrologic/hydraulic modeling through final design, permitting support, and construction administration for individual projects, as well as on-call continuing services under which multiple firms compete for individual task orders issued on an as-needed basis. Representative recent opportunities include the Town of Parker, Colorado's RFQ for design and construction documents on Chambers Road bridge and drainage work (due November 14, 2026); the City of Orlando's RQS for design services on drainwell replacement and relocation for flood mitigation funded through CDBG-DR (due October 14, 2026); Collier County's RPS for design services on Lake Park Boulevard stormwater and flow-way restoration (due November 10, 2026); and the City of Bend's RFP for South Awbrey Butte drainage improvements design with a $1.5 million design budget and $17.4 million total construction budget (due October 9, 2026).

Geographic activity in recent postings concentrates in Florida (Orlando, Tallahassee, Collier County, Pinellas County, Hillsborough County, Pasco County, Casselberry, Altamonte Springs, Sarasota County), Georgia (Statesboro, Perry, Demorest, Mableton, Drew Charter School), Colorado (Parker), and Massachusetts (Brockton, Melrose), with additional activity in Ohio, California, Texas, Oregon, Arizona, New Hampshire, and Utah. Evaluation methodologies typically emphasize qualifications-based selection under the Consultants' Competitive Negotiation Act (CCNA) in Florida and other states, with technical scoring emphasizing firm experience, personnel qualifications, project approach, and past performance; cost factors remain secondary in most professional services selections. Many solicitations carry federal compliance requirements tied to FEMA Hazard Mitigation Grant Program funding, CDBG disaster recovery programs, or Clean Water State Revolving Fund grants, necessitating Davis-Bacon wage compliance, debarment certifications, and E-Verify enrollment. Contract values where stated range from under $200,000 for specific task orders to $3.4 million for full construction engineering inspection on major corridor improvements and $17.4 million total project budgets spanning design and construction phases. The code sees consistent activity from municipalities and counties addressing aging stormwater infrastructure, flood resilience planning, and green infrastructure retrofits in both urban and suburban markets.
